Anplicatiou tiled February` 17, 1905. Serial No, 246,050.

Be it known that l, (`ii.\iii.i;s A. ."rri'ii'ri-- \'.\.\"i, a citizen ol' the liiited lntates, residing at llainlicld, iit the county of lnion and iState olx New Jersey, have invented new and uscl'ul Improvements in Frame (.'onstructioii for Folding and other .\lachiiies ol' which the following is a spccilicatioii.

-..,'l`his invention relates to an improved conio struction ot' frames which are more particularly designed for machines in which attachments require support between the side pieces thereof.

The object of this invention is toprodtice a. frame for this purpose which enables these attachments to be litted accurately and e pcditiously by means which materially icduce the cost of the sameA In the accom ianyiiig drawings, coiisistitig 2o of two sheets. Figure 1 is a sectional elevation of a folding-machine having its frame `and the means for supporting the attachments thereon constructed in accordance with my invention. Fig. 2 is a fragmentary side elevation ot' one'of the side and cross pieces and an attachment supported thereon. Fig. l is a top plan View olthe main frame of a t'oldliig-iiiachiiic embodying my invention. Fig). 4 is a vertical cross-section. on an enlarged scale. in line 4 4. Fig. 2. Fig. 5 is a vertical longitudiital section showing the connection between one of the side and cross pieces.

Similar letters of reference indicate correspoiiding parts throughout the several views.

represent the vertical standards or side pieces of the main frame. and B B B`l B R l3 ll the horizontal cross-pieces thereof. liach of the cross-pieces consists of a pair ol' .1,0 parallel rods or bars l which preferably are circular or cylindrical in cross-section and secured at their opposite ends to the adjacent side pieces of the frame. rods are seated in circular or cylindrical 45 sockets c. arranged on the inner sides of the side pieces. Although these sockets may be formed directly in the main frame. it is preferable to forni them in separate brackets l).

which are interposed between the ends ol` the 5o rods and the side pieces. Each of these brackets contains a pair of sockets on its inner side for receiving the adjacent ends of a pair of rods, and its back side has a flat face which bears against a corresponding lat facel on the inner side ol the respective side piece,

which l'accs arc arranged at right angles to The the rods l, :is shown in Figs. .2 and cross-rods, brackets, atid side pieces may be connected by various means. but preferably by screws or bolts E, which pass througi openings in the side pieces and brackets and bear with their heads against the outer side of the latter. while their inner scre\\-thread ed ends engage with correspondingly-tlireaded o )eniiigs in the ends of the rods. Each of the )olts E is axially in line with its rod and the respective socket, and upon tightening the bolt the rod is drawn with its end against the bottom ot' the socket, and the bracket is drawn against the inner side of the side piece. 1n order to cause the end of each rod to engage squarely with the bottom of its socket and insure fitting the rod and side piece together at right angles to each other,`

the outer end of each rod is concaved or dislied, as shown at 1n Fig. By this means all liability of the rod bearingr only aty its ceiitci against the bottom ol' the socket 1s avoided and the rod is compelled to bear alll around the edge or margin ot its end, pro

ditciiig a very stiil joint between the side and cross pieces and a very rigid frame as a whole.

The rods or bars of each cross-piece may be arranged either vertically one above the other or horizontally side by side, dependingI f upon the particular location in the fra-me ork the attachment which the the character of same is intended to support.

Although attachments for various purposesv l may be mounted on the cross-pieces of the frame, those shown in Fig. 1 ol the drawings consist of brackets q g, mounted on the crosspieces B`l B* and carrying the'bearings in which the rollers G of the second folding device are joiirnaled: a bracket h. mounted on the cross-piece B and supporting part of the mechanism which operates the gripper Il, whereby the sheets are side-registered before being operated upon by the blade 'i and rollers I of the first folding device; brackets j y', mount-ed on the cross-pieces B2 B3 and carrying the bearings in which the rollers J of the fourth book-folding device are journaled; bearings c k, which are mounted on the cross-pieces B2 B5 and in which are 'ournaled the upright packer or rock-shaft for operating the packers of the folded signature-stacking devices, and brackets k k2, which are mounted on cross-piece B and which support the rollers lf3 and other parts of the fourth periodical-folding device. The means for fastening each of these attachments or brackets to its cross-piece consists of two clamping-plates L- L, which are secured against opposite sides of the pair of rods by one or more bolts or screws l and either one or both of which carry parts of the particular attachment Which'is to be mounted on said rods. The clamping-bolts l preferabl vconnect the central parts of the clamp- .ing-p ates and are arranged between the rods of the cross-piece against which they bear, as shown in Figs. 1, 2, and 4.

The inner side of each clamping-plate is provided with a pairof concave recesses or seats m, which face the pair of similar recesses in the companion clampinglate. The recesses of both plates have t eir axes sepa rated the same distance as that between the axes of the rods, and the latter fit on opposite sides into the pairs of recesses in said plates, as shown in Figs. 1 and 4.

The several duplex rods, the sockets of the several supportingbrackets receiving the ends of the same, and the recesses of the sev-l eral lattachment-brackets of the machine have their axes preferabl t all arranged the same distance apart, as s own in the drawings. By this means the manufacture of the machine can be effected rapidly, accurately,

and at reduced cost, and the parts can be made interchangeable by means of standardjigs which are constructed suitable for fitting up all of the socket-brackets and attachmentbrackets. This system of frame construction also permits of forming the recesses of the attachment-brackets so that the attachments may be supported at anv desired angle relatively to the duplex rods with equal acility and also ermit of easily adjusting the attachments into the required osition which the brackets on the cross-pieces B B2 B3 B4 are either parallel or at right angles to the crossieces,while the bracket k for su porting t e fourth folding-rollers k3 on t e i side pieces and each having a pair of circular j, Tlns is apparent from ig. 1, in

, piece comprising a pair of parallel rods or crosspiece B is inclined or arranged at an obli ue angle to the rods of this cross-piece. c aim as my invention- 1.
